Modular Expansion of Goor High-Voltage Substation for a Reliable Electricity Grid
In the province Overijssel in the east of the Netherlands, we have started the initial construction works for the expansion of the Goor high-voltage substation. On a new site adjacent to the existing station, we are delivering, on behalf of Omexom and with TenneT as the end client, the civil works for a completely new 110 kV installation field. This is essential to future-proof the electricity grid and ensure continued reliability for the region. The works are part of the national Bay Replacement Programme (BRP), through which TenneT is replacing outdated high-voltage substations more quickly, intelligently, and with less disruption, and expanding them where possible. We expect to complete our works by early 2027, with commissioning scheduled for early 2028.
Through the Bay Replacement Programme (BRP) TenneT is accelerating the modernisation of high-voltage substations in the Netherlands. The approach is modular, using standard building blocks and prefabricated components—such as concrete structures and building modules—that arrive largely ready-made on site. This shortens construction time, simplifies future modifications, and reduces transport movements and on-site activities.
Electric Equipment and GROENR Concrete
Almost all on-site work is carried out using electric equipment, including excavators, pile drivers, and loaders. This not only makes operations quieter and cleaner, but also significantly reduces nitrogen and CO₂ emissions. As a result, the works can proceed within the permitted nitrogen limits, which is crucial in this area. Additionally, the prefabricated components incorporate more sustainable GROENR Concrete, which has a lower CO₂ footprint.
‘Sustainability and industrialisation are central to our strategy ‘Building a sustainable tomorrow’. The BRP approach we are applying in Goor aligns perfectly with this. The modular, repeatable solutions enable a predictable construction process with lower emissions, reduced material usage, and minimal disruption on site. In this way, we are contributing to a future-proof electricity grid, with care for the planet.’
